The pilot and co-pilot of the doomed medical transport flight that crashed into a northeast Philadelphia neighborhood and a doctor on board have been identified.

Pilot Alan Montoya and co-pilot Jesús Juárez were at the controls of the Learjet 55 as they flew a young girl who had just received “life-saving care” from a Philadelphia hospital and her mother home to Mexico, according to the outlet Milenio.

Also on board was Dr. Raul Meza, according to the Mexican emergency service XE Médica Ambulancia.

“Dr. Raúl Meza was part of [the] crew in the air ambulance XA-UCI belonging to another company where [he] also provides his professional services,” the group wrote on X, identifying Meza as their chief of neonatology.

All six people on board the plane died.

This is a developing story.
